DESCRIPTION
The MediaMatrix nWall is a surface mount CobraNet interface panel with two analog microphone/line level input channels.
The device converts audio from the input channels to a CobraNet audio stream. It can then be routed via CobraNet bundle
transmitters over a local area switched network using CAT5e UTP cable.
The nWall eliminates the need for long runs of analog microphone cables terminated in racks of patch bays as typically seen
in ballrooms and convention centers. As the connection to the nWall uses CAT5e UTP cable with network standard RJ45
crimp connectors, the installation time, number of terminations required and associated cost are all minimized. A MediaMatrix
nWall CobraNet interface panel fits within a standard 2 gang NEMA back box and is powered over the attached network
cable from a network PoE capable switch that conforms to IEEE 802.3af. The XLR connectors can be configured for multiple
audio input sensitivities (-56dBu, -26dBu and +4dBu) using a rotary switch on the front panel. Electret condenser and dynamic
microphones are supported, plus line level audio with 15V DC phantom power assigned to the XLR inputs. The 1/8th inch
(3.5mm) TRS mini jacks accept a nominal -8dBu signal that is summed to mono and mixed with the XLR inputs.
FEATURES & BENEFITS
2 balanced XLR inputs - mic/line selectable gain via front
panel 3 step rotary switch allows quick source setup at
the wall panel. XLR connector is latchless to minimize
mechanical damage to the interface panel.
2 unbalanced TRS 1/8
th
inch (3.5mm) mini jack inputs -
summed mono for PC and Aux consumer line level audio
products support off the shelf consumer audio cables.
CobraNet audio transport - via switched network and RJ45
crimp connectors greatly reduces critical path delivery time
and costs, replacing the need for skilled labor required to
solder/terminate typical analog interface panels.
Electronic patching - using MediaMatrix NWare any number
of nWall panels can be patched on the fly to any number of
NIONs, eliminating the need for expensive patch panels and
greatly reducing setup time between events.
Analog to digital - conversion at the wall panel reduces
problems with buzz, hum, ground loops and other
cable issues. It also eliminates the need for isolation and
impedance matching interfaces.

NOTE: The nWall can only be powered via an IEEE 802.3af PoE compliant network switch. This must provide up to 15.4W of DC power (minimum 44V DC and 350mA) from each individual
port over CAT5e UTP cable. Although any 802.3 compliant network switch should work with CobraNet, less expensive switches cannot operate at wire speed or have limited queue buffer
sizes and can cause problems when a large amount of network traffic is present.
